Abstract

The XXZ antiferromagnetic model (spin-l/2) in a transverse field on a double chain with a uniform long-range interactions among the z components of the spins is studied using the the Jordan-Wigner transformation and cut-off approximation. The thermodynamic quantities results like Helmholtz free energy, the internal energy, the magnetization, the specific heat ity are obtained both analytically and numerically. The results in the degenerate condition agree with that from other literatures.

Using the mean-field Jordan-Wigner transformation analysis, we have studied the one-dimensional spin-1/2 XY chain with Z-directional uniform long-range interactions in the external magnetic field. We have obtained such results as the Helmholtz free energy, internal energy, specific heat, magnetization and isothermal susceptibility. We also discuss the first and second-order phase transitions of the system at a finite temperature. Our results agree with results published in literature.
